Starter pack issues

I know this is a small issue and dont know if its been talked about.

I bought the starter pack a while ago and have only kicker, punter, Fitz and Robey coleman left. I can discard the kicker and punter but not the 2 elites. I cant put them into sets or power them up.... what am i supposed to do with them? I feel like this is an issue needs to be addressed, i hate not beeing able to get rid of items from my binder.
